I would not be as concerned with the turbulence as I am with the air having to make a sharp 90 rather than a smooth bend. It very well may be big enough to not cause a problem but if you were on the edge for airflow it would be a major restriction I would think.

Damn Rick, sorry to hear about the bad luck with the turbos.

On another subject though, as a motorcycle and porshe guy you might appreciate the layout I've working on for my motor project. :)

The crank is semi-spherical since it occupies the lower cylinder area. I wanted a super short connecting rods for maximum torque and it since it uses the crankcase as a pump I've got to keep the BDC crankcase volume to a minimum.

looks very coolSmileWavy

will it produce enough electricity to run my house?

Martini Bike Build
 

While waiting for news about the 2nd turbo rebuild I've been busy building a custom bike. The bike's colors are all old Porsche color codesSmileWavy

I should get an update this week on how the newly rebuild turbo is working out...

side project finished
 

My tunner should have turbo back from Garrett middle of next week, so dyno runs possible by next weekend. In the meantime, here's my initial startup for my bobber project:

Nice!

Woo hoo!

1999 HD 1250 Martini Bobber build
 

Here it is hitting on both cylinders:

Turbo is going back in today
 

Garrett sent our turbo back today, so it will be reinstalled for the 3rd time and tested. If all goes well dyno tuning will be scheduled for next week! We should know what kinda power this baby will make soonSmileWavy

Yeah, I'm pretty happy about it too;)

Dyno Day
 

Finally! We are planning to Dyno this pcar today. If all goes well we should have numbers later today or surly by tomorrow. Tuner said he'll try to keep it below 600hp, but I'll be more then happy with anything close to 500:eek:

In line for Dyno
 

I think today is a fine day for Dyno tuning!http://forums.pelicanparts.com/uploa...1354887234.jpg

mmmm......Porsches..... :)

Yep, it's like P-car HeavenSmileWavy

Wish my 930 was red..... DROOL!

Not fully sorted yet, but very close! 400whp was all the boost the silicone jointed intake plumbing could hold, so pulling it all off and going back with all hard piping with crimped joints that will hold all the boost we want to make...

Joining in late in the thread here - How much boost are you running and what clamps are you using? I run 18-22# on my boosted race motor (not a Porsche) and have zero problems with the silicone connections held by T-Bar clamps. Twelve different connections/clamps.

On Edit: Just found a picture - same clamps and hose I'm using. I'd think you'd be good up to the same boost I'm running.

When I worked in a large porsche restoration shop doing body work here in West Palm that sometimes had 2 or 3 IMSA GTP teams working on their Porsche 962's there during the Florida races back in the mid to late eightees I remember those cars used silicone hose and either american made aircraft grade T-bolt clamps or they doubled up on the usual Zebra or Norma German hose clamps with two side by side on each end of the hose connections.
They used american made silicone hose and T-bolt clamps and didn't use thin wall low ply chinese silicone hose or cheap chinese t-bolt clamps. I don't know what you're using on your intercooler plumbing but they didn't blow off while running higher boost than you are during the Florida 24 and 12 hour endurance races.

If using american made hose and T-bolt clamps and one blew off maybe they just need to be tightened a little more. If using worm drive hose clamps put a drop of oil on the worm gear before tightening it.

Thanks JimSmileWavy It's mostly the thin walled stuff with a mix of clamps. We will rip it all out and go back with as much hard pipe as possible eliminating most of the joints, but we will be using high quality silicone & clamps this time if any are required. This should get us over this last hurdle to our goal of 500 ponies:)

Thanks KJC, it would prolly hold the boost as set up if tweaked properly, but I'd rather have fewer joints to have to worry about so we're gonna have some hard pipe fabbed up to fit snugly that should hold anything we decide to throw at it:)
